[Bloody nipple discharge: duct ectasia]
Insights
Bloody nipple discharge in children, known as thelorrhagia, is typically benign and often resolves on its own. A watch-and-wait approach is recommended for this rare condition.
Area of Science:
- Pediatric Surgery
- Pediatric Endocrinology
- Clinical Pediatrics
Background:
- Thelorrhagia, or bloody nipple discharge, is a rare symptom in children.
- It is often mistaken for breast cancer, causing significant parental anxiety.
- The exact etiology of pediatric thelorrhagia remains unclear, with mammary duct ectasia being the most common cause.
Observation:
- This study presents two pediatric cases of thelorrhagia with similar clinical presentations.
- Both cases experienced spontaneous resolution of bleeding within 4 to 6 weeks.
- A review of existing literature on pediatric thelorrhagia was conducted.
Findings:
- Pediatric thelorrhagia is predominantly caused by benign mammary duct ectasia.
- The condition is typically self-limiting, with bleeding resolving spontaneously in most cases.
- No definitive etiology has been identified despite various theories.
Implications:
- A conservative 'watch-and-wait' approach is suggested for pediatric thelorrhagia in the absence of other concerning findings.
- Minimally invasive diagnostic studies may be considered.
- Reassurance and support for families are crucial given the benign nature and self-resolving course of the condition.
Abstract:
Bloody discharge from the nipple (thelorrhagia) is a rare symptom in childhood and is a cause of great concern due to the mistaken association with carcinoma in adults. However, in children thelorrhagia is due to benign mammary duct ectasia in the majority of cases. Up to date, only isolated case reports or case series have been published and, although different theories have been postulated, no definite etiology has been identified. We report two cases with similar clinical features and outcome, in whom bleeding resolved spontaneously 4 and 6 weeks after onset. We present a review of the literature. Based on the benign and self-limiting process and in the absence of other findings on physical examination, we suggest a watch-and-wait approach with minimally invasive studies and reassurance and support for the family as most cases resolve spontaneously.

Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine...
